Office Action

§103 §DOUBLEPATENT
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Status of claims: claims 1-19 are pending below. Information Disclosure Statement The information disclosure statement (IDS) submitted on 1/18/2025 and 2/3/2025 was filed and considered. The submission is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer. Claims 1 and 3-19 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-28 of U.S. Patent No. 11,733,150. Although the claims at issue are not identical, they are not patentably distinct from each other because the invention defined by the claims of the instant application would have been obvious to one of ordinary skill in the art in view of the claims of U.S. Patent No. 11,733,150. Independent claims 1, 18 and 19 of the instant invention is anticipated by independent claims of 1 and 20 of U.S. Patent No. 11,733,150. Dependent claims 3-17 follow likewise mapping to dependent claims 2-19 and 21-28 in U.S. Patent No. 11,733,150. Claim 3 is rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1 of U.S. Patent No. 11,733,150in view of Dong et al (US 2005/0089208). Claim 3: U.S. Patent No. 11,733,150 anticipated the following subject matter above regarding blood, but not the following which is taught by Dong et al: The apparatus according to claim 1, wherein the microscope system is configured to acquire the first and second images of the sample by acquiring first and second at least partially overlapping images of a portion of the sample (paragraph 0011, claim 14 and 29 teaches imaging with overlapping between first and second images of the sample of interest). U.S. Patent No. 11,733,150 and Dong et al are in the same field of image analysis by means of first and second image of target region using a microscope such that the combine outcome is predictable. Therefore it would have been obvious to one having ordinary skill before the effective filing date to modify U.S. Patent No. 11,733,150 by Dong et al such the images can be used to analyze image characteristics may include, for example, texture energy, entropy, contrast, and/or sharpness as disclosed in 0011. Claims 1-19 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of U.S. Patent No. 12,196,664. Although the claims at issue are not identical, they are not patentably distinct from each other because the invention defined by the claims of the instant application would have been obvious to one of ordinary skill in the art in view of the claims of U.S. Patent No. 12,196,664. Independent claims 1, 18 and 19 of the instant invention is anticipated by independent claim 1 of U.S. Patent No. 12,196,664. Dependent claims 2-17 follow likewise mapping to dependent claims 2-20 and 21-28 in U.S. Patent No. 12,196,664. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 1 and 3-19 are rejected under 35 U.S.C. 103 as being unpatentable over Ortyn et al (US 2010/0232675) in view of Lin et al (US 2004/0241677). Claim 1, similar claims 18 and 19: Ortyn et al teach the following subject matter: An apparatus for use with a microscope system, an output device, and a blood sample that was drawn from a subject (0011-0013 teaches method and apparatus for analyzing blood/erythrocyte), the apparatus comprising: a computer processor (0153-0156 teaches the require image processing including computing devices with processor such as laptop, networked, mainframe, hand-held, and other that include a processor and a memory in the execution of plurality of functions) configured to: drive the microscope system to acquire first and second images of the blood sample at respective times (0006 teaches the use of microscope for diagnostic evaluation; figure 3 part 402 teaches image data from first cell/blood and part 406 teaches image data from second cell/blood using the microscope disclosed above; 0023-0025 teaches where the cells can be acquired at different times to aid in quantifying cellular changes over time).

Claim 2 is rejected under 35 U.S.C. 103 as being unpatentable over Ortyn et al (US 2010/0232675) in view of Lin et al (US 2004/0241677) as applied to claim 1 above, and further in view of Dong et al (US 2005/0089208). Claim 2: Ortyn et al and Lin et al teaches the subject matter above regarding blood, but not the following which is taught by Dong et al: The apparatus according to claim 1, wherein the computer processor is configured to drive the microscope system to acquire the first and second images of the blood sample by driving the microscope system to acquire first and second at least partially overlapping images of a portion of the blood sample (paragraph 0011, claim 14 and 29 teaches imaging with overlapping between first and second images of the sample of interest). Ortyn et al and Lin et al and Dong et al are in the same field of image analysis by means of first and second image of target region using a microscope such that the combine outcome is predictable. Therefore it would have been obvious to one having ordinary skill before the effective filing date to modify Ortyn et al and Lin et al by Dong et al such the images can be used to analyze image characteristics may include, for example, texture energy, entropy, contrast, and/or sharpness as disclosed in 0011. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Bachelet et al (US 9,522,396) teaches Apparatus And Method For Automatic Detection Of Pathogens - FIG. 8, after the sample was dyed fluorescently the algorithm successfully tracked motion of florescent particles (indicated by arrows), and correctly identified this motion as typical in speed and direction to trypanosome parasites. An identification of trypanosome parasites was displayed onscreen. (157) 1. Prepare thin blood smears upon a cartridge, and capture images. Divide the images into fields of images. Analyze each field independently by recording a series of images from that field, effectively creating a clip of images. 2. For each frame, verify its validity using the Image Verification Module. If more than a specified number of consecutive images are poor (e.g. 4 images), report an error on this field. 3. Normalize the image to compensate for lighting variance, since typically the image is more strongly illuminated at its center. 4. For each frame in the clip, construct the background image using the Motion Field Construction Module. In thin blood samples it is possible to wait for the red blood cells to dry in order to use the simpler version of the algorithm (column 22 lines 45-67).
